A combination is a way of selecting items from a group where the order does not matter. For example, if you have a set of fruits like apples, bananas, and oranges, a combination could be choosing apples and bananas together. Unlike permutations, where the arrangement is important, combinations focus solely on the items selected. In everyday life, combinations are often used in situations like forming teams or choosing toppings for a pizza. If you want to create a pizza with cheese, pepperoni, and mushrooms, the combination of toppings matters more than the order in which you add them.
